Is Orthodontic Treatment Needed Before a Dental Implant?

Author: Assoc. Prof. Dr. Halise Aydemir, Orthodontic Specialist.

Orthodontic treatment is not needed before every dental implant. Preparation may be considered when the space for the replacement tooth or the positions of neighbouring teeth need adjustment. The decision is not based on the visible gap alone. Having the implant clinician and orthodontist agree on the final goal and treatment sequence provides a clearer path than starting two independent treatments.

Why assess tooth and root positions before planning an implant?

Orthodontic preparation may be considered to create suitable space for a missing tooth or adjust neighbouring natural teeth. It is not compulsory for every implant candidate. A wide visible gap alone does not establish that all implant requirements have been met.

The visible crown and the root within the bone may point in different directions. Space between crowns can coexist with different root positions, and teeth may have tilted towards the missing tooth. Roots, bite and supporting tissues are therefore assessed together, rather than the gap in a smile photograph alone. No single millimetre measurement or imaging method applies to everyone.

The AAO glossary explains that orthodontics can open or preserve space for an implant. The Guy’s and St Thomas’ NHS guide also distinguishes closing gaps by moving teeth from preparing space for replacement teeth in congenital absence. A plan for a congenitally missing tooth does not automatically apply to a tooth lost later.

Assessment	Why it matters
Visible space	Its relationship with the intended size and appearance of the replacement tooth is assessed.
Neighbouring tooth inclinations and roots	Tooth positions beneath the visible surface space are examined.
Bite with opposing teeth	The replacement tooth's chewing relationship is planned.
Bone and gum condition	The relevant clinician assesses implant suitability and additional needs.
Growth and existing restorations	These may affect sequencing and temporary solutions.

Hypothetical example: In an adult whose neighbouring teeth have tilted into the gap, repositioning may be discussed first. Another person's natural teeth may already be suitably positioned, without a need for orthodontic preparation. It would be incorrect to tell both that braces are always necessary before an implant.

This article does not set surgical implant placement criteria. Its main purpose is to help explain which tooth movement is being proposed. If space closure has not yet been considered, clarify the overall goal through the orthodontic options for missing teeth first.

Which comes first: orthodontics or the implant?

If natural tooth positions will change, it is important to assess those movements in a joint plan before implant placement. An implant behaves differently from a natural tooth: once placed in bone, it cannot be moved like natural teeth using conventional orthodontic forces. The AAO states this distinction. Later use of braces or aligners does not mean the implant can be moved to a new position.

This is not an unchanging rule that the implant must always be last. An existing implant, a planned new implant and a need for limited movement are different starting points. Areas that will move and positions that must be maintained are assessed together.

The overall sequence can be understood as follows:

1. Define the final goal. Will the gap receive a replacement tooth or be closed orthodontically?
2. Identify necessary natural tooth movements. Which tooth needs repositioning, and why?
3. Assess implant and restorative needs jointly. Space, roots, bite and tissue conditions are discussed with the relevant clinicians.
4. Review preparation. Check whether the target position has been reached, rather than elapsed time alone.
5. Connect the next procedure with the preservation plan. Determine how tooth positions and any temporary tooth needs will be managed while waiting.

These steps explain coordinated planning; they are not a surgical sequence or standard clinical protocol for everyone.

Hypothetical example: Someone with an implant appointment who is also considering movement of neighbouring teeth needs the plans checked for compatibility before the implant position is finalised. If an implant already exists, natural tooth movement is assessed around that fixed position. An existing implant does not automatically rule out orthodontics, but may affect options and limits.

Timing requires additional consideration in growing patients. The NHS hypodontia guide states that implants are not suitable during ongoing growth; chronological age alone does not establish growth completion. Any temporary solution should be planned alongside orthodontic and restorative goals.

How is readiness for the next stage established, and what happens while waiting?

Preparation does not end merely because the gap looks neater in a photograph. The orthodontist and the clinician planning the implant and restoration should jointly review the original goals. It should be clear which natural tooth needs to reach which position and what conditions allow the next stage to begin.

Bring information about why and when the tooth was lost, previous records, temporary teeth or restorations and other clinicians' recommendations. These records do not eliminate every need for new imaging; the examination determines which records answer the current question. Existing implants and their restorations are included in planning.

Part of the plan	What needs clarification
Orthodontic preparation	Which teeth will move and towards which goal.
Review of preparation	Which findings will be reassessed before the next procedure.
Tissue assessment	Which clinician will address additional implant-related needs.
Temporary tooth	How appearance and function will be managed between stages, if needed.
Preserving the space	How tooth positions will be monitored during the wait.
Fees and follow-up	The separate scopes of orthodontics, implant placement, restoration and retention.

Hypothetical example: If space has been prepared but implant placement will not follow immediately, the waiting period may not be a period of doing nothing. Space preservation, tooth positions, care and temporary solutions belong in the individual plan. Someone else's retainer or an old aligner is not a substitute.

Active gum disease, decay or other oral health issues may also affect sequencing. The guide to gum assessment before orthodontics explains why supporting tissues are assessed before tooth movement. The priority is to connect stages safely, rather than skip assessment to avoid changing an implant date.

After consultation, you should understand the reasons behind the sequence, rather than simply hearing braces first, implant later. If orthodontics is not recommended, the findings supporting that decision can also be explained. The adult orthodontics guide covers general suitability. Individual timing, measurements and sequencing require examination and joint planning.

What should be clarified if two clinicians offer different recommendations?

The first question is whether both recommendations share the same final goal, rather than which clinician should act first. One consultation may have considered the visible gap while another also considered neighbouring tooth movement or the replacement tooth's shape. Asking for the records and goals behind the recommendations to be reviewed together is more useful than deciding the order yourself.

For example, a hypothetical patient may be told there is enough implant space, while an orthodontic consultation recommends correcting a neighbouring tooth's inclination. These statements are not necessarily contradictory: visible space and root positions are separate considerations. Joint discussion should explain which tooth would move in which direction, how this relates to the planned implant position and how preparation will be checked. This example does not prove orthodontics is needed in a specific patient; it illustrates why recommendations may answer different questions.

Share existing records and earlier recommendations with both teams. If further investigation is requested, ask which question it will answer; an image taken elsewhere may not answer every question. Clarify three points before leaving:

• Which team will contact you about the next stage?
• How will space and tooth positions be preserved while waiting?
• Which findings will establish readiness for the next procedure?

An article cannot determine exact surgical measurements, dates or amounts of tooth movement; these need explanation in your individual plan.
